<input type="hidden" name="my_id" id="my_id" value="1">
<ul class="myList clearfix" id="thismyList">
<li class="myBullet" id="answer1">blabla1</li>
<li class="myBullet" id="answer2">blabla2</li>
<li class="myBullet" id="answer3">blabla3</li>
In this page I want to something like this:
if document.getElementById('my_id').value=="1"
document.getElementById('answer1').click;
if document.getElementById('my_id').value=="2"
document.getElementById('answer3').click;
if document.getElementById('my_id').value=="3"
document.getElementById('answer1').click;
if document.getElementById('my_id').value=="4"
document.getElementById('answer2').click;
I write this to show what I want. I know that code is wrong. But I think that explains what I want. How can I do that?
The correct syntax for that would be:
switch (document.getElementById('my_id').value) {
case "1":
document.getElementById ('answer1').click ();
break;
case "2":
document.getElementById ('answer3').click ();
break;
case "3":
document.getElementById ('answer1').click ();
break;
case "4":
document.getElementById ('answer2').click ();
break;
default:
break;
}
Note that in some cases, you may need to trigger mouse events like in this answer .
IF you want to invoke the click behaviour of a function you should just call.
document.getElementById('id').click();
I think it should works like you did without the '()' also.
